ibase_execute

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

ibase_execute -- Execute a previously prepared query

Description

resource ibase_execute ( resource query [, mixed bind_arg [, mixed ...]] )

Execute a query prepared by ibase_prepare(). If the query raises an error, returns FALSE. If it is successful and there is a (possibly empty) result set (such as with a SELECT query), returns a result identifier. If the query was successful and there were no results, returns TRUE.

This is a lot more effective than using ibase_query() if you are repeating a same kind of query several times with only some parameters changing.

Przykład 1. ibase_execute() example

<?php

                   

                $dbh = ibase_connect($host, $username, $password); 

                
$updates = array(

                    1 => 'Eric',

                    5 => 'Filip',

                    7 => 'Larry'
);

                
$query = ibase_prepare($dbh, "UPDATE FOO SET BAR = ? WHERE BAZ = ?");


                

                foreach ($updates as $baz => $bar) {

                    ibase_execute($query, $bar, $baz);

                }

                
?>

Notatka: In PHP 5.0.0 and up, this function returns the number of rows affected by the query (if > 0 and applicable to the statement type). A query that succeeded, but did not affect any rows (e.g. an UPDATE of a non-existent record) will return TRUE.
